Paramagnetic O2 Purity Analyzer Operational Theory
Operational Theory
2.1 Introduction
The analyzer is composed of three subsystems:
1. Paramagnetic Sensor
2. Sample System
3. Electronic Signal Processing, Display and Control
The paramagnetic sensor and the sample system are located in the
Analysis Unit while the Electronic Signal Processing, Display and Control
systems are housed in the Control Unit.
The sample system is designed to accept the sample gas and transport
it through the analyzer without contaminating or altering the sample prior
to analysis. It is described in detail in Part II Section 6.4 of this manual.
The Analysis Unit is separate from the Control Unit in order to
provide critical temperature stability. The paramagnetic sensor is an
electromechanical device that translates the amount of oxygen present in
the sample into an electrical signal. It is a partial pressure device sensitive
to both operating pressure (vent pressure) and temperature fluctuations.
The output from the sensor is compensated for pressure variation using a
baseline pressure initially set during calibration. Temperature at the sensor
is held constant using an 80 Watt heater controlled by a PID temperature
controller located in the Control Unit. Feedback from the sensor to the
PID controller is supplied by an RTD installed in the Analysis Unit. The
paramagnetic sensor is described in Part II Section 6.2.
The electronic signal processing, display and control subsystem
simplifies operation of the analyzer and accurately processes the sampled
data. The microprocessor controls all signal processing, input/output and
display functions for the analyzer. Figure 2-1 is a block diagram for the
Control Unit and Figure 2-2 is a block diagram for the Analysis Unit.
These diagrams indicate the functionality of each unit and the interaction
between them.

Paramagnetic O2 Purity Analyzer Operational Theory
2.2 Electronics and Signal Processing
The Model 3010MAParamagnetic Oxygen Purity Analyzer uses an
8031 microcontroller with 32 kB of RAM and 128 kB of ROM to control
all signal processing, input/output, and display functions for the analyzer.
System power is supplied from a universal power supply module designed
to be compatible with any international power source (Note: the heating
system for the analysis must be set to 115V or 230V with the line
voltage selector switch located on the rear Control unit). With the
exception of the paramagnetic sensor, all of the system electronics are
located in the Control Unit. Figure 2-3 shows the location of the
temperature controller and the main electronic PC boards.
Figure 2-3: Location of Electronic Components in Control Unit
The universal power supply is located behind the temperature
controller and is accessible after removing the rear panel.
The signal processing electronics including the microprocessor,
analog to digital, and digital to analog converters are located on the
motherboard at the bottom of the case. The preamplifier board is mounted
on top of the motherboard as shown in the above figure. These boards are
accessible after removing the rear panel. Figure 2-4 is a block diagram of
the analyzer electronics.
Teledyne Analytical Instruments 21
Part 1 Control Unit Model 3010MA
When an oxygen level is present, the paramagnetic sensor in the
Analysis Unit generates a voltage in the range of 0 to 1VDC. The voltage
is passed to the Control Unit via the sensor cable between the Analysis
Unit and the Control Unit. A voltage amplifier in the Control Unit
conditions the signal and passes it to the 18-bit analog to digital (A/D)
converter which is controlled by the microprocessor.
The sensor’s vent pressure from the Analysis unit is received via a 1/8
inch gas connection on the rear of the control unit. The vent pressure is
then routed to the pressure transducer located on the pre-amp PCB. The
output from the sensor is condition by a two-stage amplifier and passed to
the A/D converter.
The concentration signal, pressure signal, and the input from the
control panel are processed by the microprocessor, and appropriate control
signals are directed to the display, alarms and communications port.
The same digital information is also sent to a 12 bit digital to analog
converter that produces the 4-20 mA dc and the 0-1VDC analog
concentration signal outputs, and the analog range ID outputs.
The microprocessor monitors the power supply, and activates the
system failure alarm if a malfunction is detected.
2.5 Temperature Control
For accurate analysis this instrument is temperature controlled to
provide a thermally stable environment. The analyzer must be brought to
thermal equilibrium prior to analyzing any sample gas. The paramagnetic
sensor is sensitive to operating temperature variations. The sensor module
used in the Model 3010MA includes a pre-amp and an internal
temperature controller set to 55C. The sensor module is also housed in an
insulated temperature controlled oven within the Analysis Unit to improve
thermal stability and isolate the system from any external temperature
fluctuation. The oven temperature is maintained at a constant 40C by the
PID temperature controller located in the Control Unit (see Figure 2-3).
Feedback to the temperature controller is by an RTD on the sensor
mounting block. The oven is capable of providing a maximum of 80
Watts.
